A project can be run in the Final Builder IDE. But when it was run by the command line tool, FBCMD report error: “Error converting string to date/time”.
I was able to make your project run fine, on the GetDateTime action, make sure the formatstring is valid for your local, on mine I changed it to dd/mm/yyyy and the project ran fine in the ide and the console. Are you running the console under the same user as the IDE?
